Cotton has long been praised for its breathability, but when it comes to period care, relying on 100% cotton doesn’t always feel great.
Cotton absorbs moisture and then holds onto it. That’s why hikers and athletes are warned against cotton layers: once they get wet, they stay wet. The same logic applies to organic period panties. During a heavy flow or long day, fully organic cotton can leave you feeling damp, sticky, or even chilled. Those hours at work, running errands, or managing cramps at home deserve better coverage without the unwanted, soggy aftermath.
Rather than only using cotton, we designed our natural period underwear with a deliberate mix of organic fibers and performance-based fabrics. This blend creates a breathable, skin-friendly fit that still wicks moisture away from your body. You get the softness of cotton where it matters most, supported by flexible, fast-drying layers that hold up through long commutes, workouts, and hormonal shifts.
Meet the Saalt Difference: Drier, Softer, Smarter
Organic period underwear doesn’t have to mean soggy seams or outdated designs. We’ve combined breathable, natural cotton fibers with innovative moisture-wicking technology to create a fit that feels familiar and performs through every phase of your cycle. Here’s how our design helps you stay dry, feel confident, and finally trust what you’re wearing.
Soft Materials That Respect Skin
A comfortable pair of natural period underwear should never leave you chafed or itchy. That’s why we use body-conscious blends of biodegradable cotton fiber and flexible synthetics that skip harsh dyes and avoid PFAS. Each pair feels breathable from the first wear and stays smooth through long shifts, class, or those slower days spent resting at home. No clingy, synthetic feel, and no stiff seams.
Built-In Layers Designed for Period Health
Layering matters, especially when managing discharge, spotting, or heavier flows. Our gusset features three layers: a moisture-wicking top, an absorbent inner core, and a breathable back panel that pulls moisture away from the skin. This keeps your vulva dry and helps reduce irritation and bacterial overgrowth, common concerns with fully organic options that hold wetness close.
Our moisture-wicking underwear fits smoothly under clothes and adapts to your body’s needs. For heavier days, many pair them with a menstrual cup or period disc for added peace of mind.
So Dry You Might Forget You’re Wearing It
No one wants to sit through a meeting or walk into a date night with sagging fabric between their legs. That’s why our gusset is one of the driest on the market, designed to hold up to eight regular tampons’ worth of fluid while staying light and discreet. Organic cotton period panties from Saalt never feel bulky, and you won’t need to adjust or second-guess your coverage during the day.
Period Care That Goes the Extra Mile
Better underwear means fewer leaks and less waste. Our materials include a mix of biodegradable fabrics that offer long-term durability without compromising skin comfort. These styles are built to last, without harsh chemical processing or shortcuts. As a certified B Corp, we hold ourselves to high standards for people and the planet.
A Fit That Evolves With You
Cycles change. Bodies heal. Hormones fluctuate. Your period care should keep up. Our underwear fits are designed to adapt through every stage, from a teen’s first cycle to recovery after childbirth or hysterectomy. With options that mirror your favorite everyday pairs, period underwear organic becomes something you can reach for every month.
Choosing the Right Absorbency Level for You
Everyone’s flow comes with different rhythms—some cycles shift with hormonal changes, some feel heavier after surgery or childbirth, and others taper off with just a hint of spotting. That’s why we offer multiple absorbency levels across our period underwear collection, including breathable blends that don’t sacrifice comfort. Use this guide to decide which absorbency level feels right for your flow, routine, and comfort preferences.
- Zero Absorbency (No leakproof gusset): Made for non-period days when you want breathable underwear with a natural-fiber cotton gusset. Ideal for workouts, non-period days, or post-cycle cooldowns.
- Light Absorbency (Holds 2+ light tampons or one liner): Great for spotting or as backup with a menstrual cup or period disc. Many wearers use this level at the start or end of their cycle, or for hormonal spotting and sweat-wicking during the day.
- Regular Absorbency (Holds up to 3 tampons or 2 pads): A steady choice for typical flow days, errands, work, or class. Also works for those managing light bladder leaks or mid-cycle spotting caused by birth control.
- Heavy Absorbency (Holds 4 tampons or 3 pads): Reliable protection for heavier flow days, overnight use, or postpartum bleeding. A go-to for anyone who needs longer wear without frequent changes, especially on the first day or two of a cycle.
- Super Absorbency (Holds 8+ tampons or 6+ pads): Built for intense flow, hormonal shifts, postpartum recovery, or extended wear during long shifts and travel. This level gives you coverage that holds up during the toughest parts of your cycle.
The Importance of Period Products Made Without PFAS
Anyone who menstruates knows how personal period care really is. The fabric that sits against your body for hours at a time should be safe. PFAS, also known as “forever chemicals,” have shown up in some conventional period underwear, but they don’t belong anywhere near your cycle.
- PFAS Can Interfere With Hormone Balance: These chemicals build up in the body over time. Because some PFAS are known endocrine disruptors, there’s growing concern about their potential impact during hormonally sensitive life stages like puberty, menopause, or post-surgical recovery.
- Wearing PFAS-Treated Fabric Against Sensitive Areas Increases Exposure: Period underwear stays close to absorbent skin for long stretches, through school, sleep, workouts, and stressful days. Exposure from this kind of contact adds up quickly, even more so for those with longer wear time.
- PFAS Exposure Has Been Linked to Serious Health Concerns: Research points to immune disruption, fertility complications, and even increased cancer risk over time.
- These Chemicals Don’t Go Away Once You Toss Them: PFAS stay in landfills, leach into soil and water, and pollute the environment long after your cycle ends. Choosing safer period underwear reflects a bigger commitment to health, yours and the planet’s.
- Products Made Without PFAS Give You Peace Of Mind: When you choose period underwear made without forever chemicals, you're choosing transparency and trust. Every pair from Saalt is designed to protect your body without relying on shortcuts or harmful coatings.
Combining Our Organic Period Underwear with Other Reusables
Some days require more coverage than others. While organic-style period underwear is breathable, soft, and made with biodegradable natural fiber, combining it with other reusable options can create a more flexible setup, one that gives you the protection you need without overthinking every bathroom break. On lighter days, period underwear alone may be enough. But during heavier flows, long commutes, or overnight wear, adding internal protection can bring extra peace of mind.
A menstrual cup or period disc pairs easily with our leakproof underwear. The layered gusset stays low-profile under clothes, so wearing both doesn’t feel bulky or restrictive. Many people use this combo for long shifts, travel days, or when privacy is limited. It helps reduce bathroom urgency and lowers the chance of leaks when comfort matters most.
Choosing reusables doesn’t have to feel like a lifestyle overhaul. Building a system that fits your routine, one that blends internal and external care, makes it easier to stay consistent. There may be trial and error at first, but finding what works creates a rhythm you can rely on through hormonal shifts, recovery, or a simple desire to reduce waste.
For those curious about placement or comfort, our guide on how to insert a menstrual disc walks you through the process.
